HOLDER FOR PAPERS, PAMPHLETS, OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 514,987, dated February20, 1894.

Application filed August 1, 1893. Serial No. 482.102- (No model.)

To all whom it may concern.-

Be it known that I, FRANCIS BUNBURY Frrz- GERALD CAMPBELL, librarian, asubject of Her Majesty the Queen of Great Britain and Ireland, residingat 29 Avonmore Road, Vest Kensington,London, in the county of Middlesex,England, have invented certain Improvements in and Relating to Holdersor Cases for Papers, Pamphlets, Reports, Periodicals, Music, and theLike, of which the following is a specification.

This invention relates to holders or cases for papers, pamphlets,reports, periodicals, music, and the like, and its object is to providea holder or case of simple and economical construction, the containingcapacityof which may readily be varied to suit the thickness of thearticles it is intended to hold.

A holder or case constructed in accordance with my invention somewhatresembles the cover of a book and consists of two leaves or covers ofmillboard, wood, or other suitable fairly rigid material connectedtogether by a band or strip of some suitable flexible material, such asleather or cloth, forming a back.

The main feature of my invention, as will be hereinafter more clearlyset forth consists in so connecting the flexible back with the leaves orcovers as that the lines of junction of said back with the leaves orcovers may be readily varied at will, and this I eifect by passing thesides of the band or strip forn1= ing, the back through slits ornarrowapertures formed near the edges of the leaves or covers, said slits ornarrow apertures may be either cut in the leaves or covers, or producedby securing bands, strips, rods, or clips of suitable material, such ascanvas, webbing, or metal, thereto. By drawing one or both sides of theback inward or outward through the said slits or narrow apertures, thewidth of the material forming the back, between its lines of junctionwith the leaves, may obviously be lessened or increased as desired.

Any suitable means such as holding straps, tapes, clips, and the like,connecting the back with the leaves or covers, may be employed forsecuring the back in the position to which it has been adjusted, but thefriction or grip between the same and the slits or narrow aperturesthrough which it passes would probably in most cases be found to besufficient.

In the accompanying drawings in which similar letters refer tocorresponding parts in all the figuresz-Figure 1 is a plan of the innerface of one of the leaves or covers showing the connection between thesame and the adjustable flexible back. Fig. 2 is a trans verse sectionof the case or holder on line 12 Fig. 1. Fig. 3 is a plan and Fig. 4 atransverse section on line 3et Fig. 3 showing a slightly modifiedarrangement. Fig. 5 is a plan and Fig. 6 a transverse section on line 56Fig. 5 of another slight modification. Fig. 7 is a plan illustrating aslight modification of the arrangement shown in Figs 5 and 6.

or represents one of the leaves or covers and b is the adjustableflexible back.

In Figs. 1 and 2 the back I) is represented as connected with the leavesor covers a by passing through slits or narrow apertures C out in thelatter. cl. d. are straps preferably of webbing or other rough facedmaterial tightly stretched across the inner faces of the covers a underwhich straps the sides of the back I) are passed. The rough faces of thestraps d pressing tightly against the surface of the back I) will retainthe same in the position to which it has been adjusted.

In Figs. 3 and t in lieu of slits or narrow apertures 0 cut in theleaves or covers a, I represent narrow apertures or slits for thepassage of the back I) as formed by securing thin metal rods 0' parallelto the edges of the leaves or covers a.

In Figs. 5 and 6 narrow apertures or slits for the passage of theback 1) are shown as produced by straps or bands 0 preferably of thinsheet metal or webbing secured over the inner faces of the covers a neartheir edges.

Fig. 7 shows the slits or narrow apertures for the passage of the backI) as produced by the clips 0 secured to the covers a. In all cases theadjustment of the back I) is etfected by drawing one or both sides ofthe same inward or outward in regard to the leaves or covers at, eitherthrough the slits c, or through the narrow apertures or slits producedbe tween the covers and the rods, straps, or clips 0 c and 0 If desiredthe straps 015 may in many cases be dispensed with, as the friction orgrip between the back I) and the slits 'or narrow apertures throughwhich it passes may in many cases prove sufficient to retain the back I)in the desired position.

In order to prevent accidental disconnection of the leaves or covers andback, I prefer to thicken the edges of the backbin some convenientmanner, as by cords stitched therein (shown at 1)) thereby preventingthe accidental withdrawal of the back I) through the slits or narrowapertures through which it passes. The said thickened edges b may alsoin some cases serve to assist in retaining the back in the position towhich it has been adjusted.

By the employment of myimproved holder or case, it will be seenthatwhatever the thickness of the contents thereof, the leaves or covers amay be caused, by adjustment of the back I) as before explained, to lieflat upon and in close contact with the whole surface of such contents;there will also be no bulg What I claim, and desire to secure by Letters Patent of the United States, is

1. In combination in an adjustable binder the two covers or sides andthe adjustable flexible back connectingthe same, said back passingthrough apertures at the edges of the covers and the strap cl secured tothe inner side of the cover to receive the free end of the back betweenitself and the cover, substantially as described.

2. In combination in an adjustable binder,

the two covers or sides, and the adjustable flexible back connecting thesame, said back passing through apertures at the edges of the covers andthe strap cl extending along the inner side of the covers to receive thefree end of the back between itself and the cover, the edge of said freeend beingthickened, substantially as described.

1 In testimony whereof I have signed my name to this specification, inthe presence of two subscribing witnesses, this 20th day of July, A. D.1893.
